The Quinta dos Castelares Estate is located in the Freixo de Espada à Cinta area, in the Douro Superior, framed by the Natural Park. Our production methods seek to preserve the ancestral farming techniques combined with the latest developments in viticulture, leading to greater environmental sustainability and respect for the nature. The low level of mechanization - where the grapes are picked by hand to small boxes - and low yields per hectare are the best example of that. In the several vineyards of the estate we seek to take advantage of the uniqueness of each location.
